Iterated function systems can be used to draw various kinds of fractals.
Some of the most famous ones are the Sierpinski triangle and Barnsley's
fern. DrawIFS implements a simple language for describing such systems (and
some other select ones, such as the Henon map), and draws images based on
these descriptions. Features include automatic scaling and centering and two
different ways of colouring the image with support for custom palettes. The
archive also contains numerous example fractals, both well-known and more
obscure.

   These are the changes in version 1.2 --

 * It is now possible to define new numerical constants, which is useful
when certain numbers need to be used several times in the same fractal
definition.

 * Introduced the de Jong map, another non-affine transformation.

 * The expression parser now recognizes 'rnd' to mean a random number,
allowing for fractals which are different every time they are rendered.

 * The formulae for all the transformations implemented by DrawIFS are now
documented in the manual.

 * Added even more example fractals.
